The Crack Investigation and Analysis of Frame Structure Subjected to Lateral Loading

Abstract

The crack development of two cast-in-situ RC frame structures subjected to lateral loading was investigated. Then the develop reasons were analyzed. The investigation indicates that the existence of monolithic slab in reinforced concrete frame structure overstrengthened the actual flexural capability of longitudinal beams. Therefore, the participation of monolithic slabs should be made in consideration in structural design to achieve the strong column weak beam philosophy.
